How to fix black screen and flickering lines at launch

Important Note :

ⓘ This guide is currently *outdated* and I recommend you to check my improved one for Company of Heroes here :

ⓘ This is an old copy of the guide I've made for Vanilla Company of Heroes. I selected the wrong game and that's how it ended up in Blitzkrieg. I finally chose to leave it, just in case someone in need finds it from here instead.

This is the only stable way I found to fix the black or flickering screen issue when you launch CoH for the first time (or after reinstall).

➜ I'll assume your video drivers are up to date and that your rig is better than a low-cost toaster from the 80's

I. Making sure your game installation is clean.

It may seem obvious, but if you have any other mod interfering with your game from previous installations or corrupted settings folder, I can't help you.

if there is one, I suggest you to fully delete the folder named "Company of Heroes Relaunch" located in "C:\Users\yourname\Documents\My Games\" .

II. Launching the game in "safe-mode"

*Navigate to your game folder from Steam by right clicking Company of Heroes > Properties > Game Files > Open game folder or through the Windows Explorer at "C:\Program Files (x86)\Steam\steamapps\common\Company of Heroes Relaunch" (default).

*Find "RelicCOH.exe" and right click > properties > Compatibility : make sure everything is unchecked.

*Rename "RelicCOH.exe" to "RelicCOH -minvidmem 0.exe".
Please be careful to not have .exe twice ( ex: "RelicCOH -minvidmem 0.exe.exe")

*Double click RelicCOH -minvidmem 0.exe. The game now should open with default video settings and a working display (even if performances are very poor: cursor lagging etc. You're not supposed to play like that).

*Navigate to video settings and change to your native resolution. Make sure to have every settings set on "HIGH" and not "ULTRA". Press "apply" and "OK" once the game ask you to.

Now the game will use DX9 instead of DX10 and the problem should be gone.

III. Cleaning the mess

* Leave the game.

* Go back to your game's folder and rename "RelicCOH -minvidmem 0.exe" to "RelicCOH.exe".

ⓘ If you skip this step, Steam will consider the .exe to be missing and it will download the file again. Mods like Blitzkrieg will not start either.

IV. Congratulations! You're done!

ⓘ If your game still doesn't work, you can try this additional fix :

* Go back to "RelicCOH.exe" and right click > properties > Compatibility.

* Check "Disable Fullscreen Optimizations".

* Hit "save".

I hope this short tutorial saved you a few hours of free time and prevented an incoming headache. Let me know if you have any other magic fix concerning black screen & flickering issues at launch or in game.

yea i had the problem and when i turned on - anti-aliasing it fixed it but still thanks.

@spikes In most cases you can't even get to the main menu. Changing anti-aliasing (which was on by default) didn't fix the issue alone, once I managed to edit settings and revert the previous fix ; or at least in my case. But thanks for the tip if it ever works for someone else.

or you could just go to settings and put on antilaising i dont think i spelled it right but its much simpler
